Granted: 1995-10-24
Abstract: A system for improved cooling of a photosensitive coating on a moving substrate comprising a reflector block and ultraviolet lamp assembly, a refrigerating device, water circulation system and control system.  The reflector-block includes two longitudinally extending cooling conduits and is substantially completely cooled by refrigerated water circulated through such conduits within a temperature range monitored and regulated by the control system.  The temperature of the reflector-block of the apparatus is controlled for curing of a photosensitive coating on a moving substrate.  The reflector-block is operated at a temperature range between about 50°F. to 90°F. by water circulated through the reflector-block conduits, which water is cooled by a refrigerating device to a temperature within a range between about 45°F. to 75°F. The temperature of the cooled water is monitored and controlled in a manner to start the refrigerating device when signals from a temperature monitoring device indicate the cooled liquid has deviated from an established temperature range.
